ACID-BASE TITRATIONS - Columbia University

1. ACID-BASE TITRATIONS . In this exercise you will use Excel to construct titration curves for a titration between a strong acid and strong base and between a weak acid and strong base . To set up a spreadsheet for the titration between a strong acid and strong base is quite straightforward, and you will use this as a way of getting practice for setting up the spreadsheet for the weak acid strong base titration. At the end of the exercise you should hand in print outs of the plots you created and answers to the questions in each section. A titration curve is a plot of solution pH in a flask vs. volume of titrant (solution in the buret). Figure 1 shows a titration curve for a strong acid strong base , where the acid is in the flask and the base in the buret. As base is added to the acid solution, the pH of the solution in the flask increases slowly at first, then very sharply and then again slowly.

2 titration curve (pH of solution in flask vs. volume of NaOH added to flask) similar to the one shown in figure 1. Looking at the titration curve in figure 1, you can see that before any
